Two US Banks that “Nailed” Cashback & Loyalty — What They Did, What It Cost, and What Changed
Cashback and loyalty programs aren’t just marketing gimmicks — for some banks, they’re billion-dollar engagement machines.
Two of the best examples in the U.S. market are American Express and Discover. Both have refined their loyalty ecosystems to drive customer acquisition, spending, and retention — but they’ve done it in very different ways.
This post breaks down:
-
How each program works
-
Annual and quarterly budgets
-
Before-and-after results after major program changes

Lessons you can apply to your business

How the open-source ACHIVX platform can help replicate these strategies at any scale
American Express: Premium Rewards at Scale
Program Overview
American Express’ Membership Rewards (MR) program is the centerpiece of its premium card strategy. It’s designed for high-spend customers, with points redeemable for travel, statement credits, gift cards, or transfers to partner loyalty programs. Co-brand cards with Delta, Hilton, and Marriott add even more earning potential, often with partner-funded perks.
What They Spend
Amex is unusually transparent about loyalty costs, reporting “Card Member rewards” as a standalone expense:
-
FY2024: $16.599 billion (2024 Annual Report, Table 4)
-
Q1 2025: $4.378 billion (Q1 2025 10-Q)
-
Q2 2025: $4.618 billion (Q2 2025 10-Q)
Half-year total for 2025: $8.996 billion.
The Impact of a Premium Refresh
While MR has existed for decades, a major program refresh in 2017–2018 marked a turning point:
-
2018: Record 12 million new cards issued after revamping Platinum and other products (Press Release)
-
2019: Proprietary billed business hit $1.071 trillion, with 70M cards in force (2019 Annual Report)
Customer engagement is high — the Ultimate Redemption Rate for MR points remains around 96%, meaning almost all earned points get used (Q1 2025 10-Q) .
Discover: Simple Cashback, Smart Acquisition Hook
Program Overview
Discover’s loyalty program is built around straightforward cashback:
-
5% rotating quarterly categories (with activation, capped)
-
1% base cashback on all other purchases
-
Cashback Match — doubles all cashback earned in the first year for new cardmembers
The Cashback Match offer launched in 2015 (Press Release) and quickly became a defining acquisition tool.
What They Spend
Discover books rewards as a reduction of net interchange and discount revenue:
-
FY2024: $3.0 billion (2024 10-K, R59 footnote)
-
Q1 2025: $703 million (Q1 2025 10-Q, R43 footnote)
For comparison, in Q2 2020 rewards totaled $385 million — showing significant growth over time (Q2 2020 footnote) .
Discover also tracks a rewards rate (rewards as % of sales volume). In Q4 2024, this was 1.35%, down from 1.44% the year prior, showing active cost management (PaymentsDive) .
Side-by-Side: Budgets & Strategies
| Metric | American Express | Discover |
|---|---|---|
| Annual Loyalty Spend (2024) | $16.6B | $3.0B |
| Latest Quarterly Spend | $4.618B (Q2’25) | $703M (Q1’25) |
| Program Core | Points + partner transfers, premium benefits | Straight cashback + year-1 match |
| Notable Tactic | Co-funding via partners | Time-boxed acquisition bonus |
| Redemption Rate (URR) | ~96% | N/A (but high cashback usage) |
| First-Year Boost | None specific | Cashback Match (doubles earnings) |
What Any Business Can Learn
-
Make value clear — Whether it’s MR points or simple cashback, customers must immediately understand the benefit.
-
Tie offers to lifecycle — Discover’s year-1 boost drives early engagement; Amex’s premium benefits keep high-value customers.
-
Track rewards as a cost line — Both banks publish this quarterly, allowing precise ROI measurement.
-
Encourage redemption — High redemption = high perceived value = better retention.
-
Use partner funding — Co-branded or affiliate partnerships can offset program costs.
